1. Introduction
Congratulations on your purchase of the Rocktron Prophesy™!
Effectively comprising three complete processors in a single package, the Prophesy is the single most powerful
and sophisticated guitar system available today. With dual 24-bit, 66MHz DSP processors providing 130mips of
processing power, the Prophesy is over 12 times as powerful as the original Rocktron Intellifex!
The pre-effects section features wah, compression, EQ, and numerous other effects that can be assigned prior
to the preamp section. The highly-configurable post-effects section provides ultra-transparent, high quality
effects which completely preserve the tone of the preamp—thick reverbs and lush choruses can be used
without coloring the sound of the preamp's tone.
The preamp section features four channels
(Clean American, Texas Blues, Vintage British
and Mega Drive), each with their own distinct
voicings to provide a vast array of amp sounds
to the player — especially when combined with
the pre and post parametric EQ.
The ADSR (Attack/Decay/Sustain/Release)
function features Rocktron's patent-pending
pluck detection, and allows you to configure
specific Prophesy parameters to be controlled
dynamically by each pluck of a guitar string.
Getting Started
Often the large number of display pages and
preset parameters in a product such as the
Prophesy can seem a little overwhelming to a
new user. Once you have become familiar with
the basic operating interface of the Prophesy,
we encourage you to study the Performance
Notes section in the Appendix of this manual.
The Performance Notes section describes how
many of the factory presets were created, and
discusses how to get a particular distortion
sound, which effects are used, etc. You can
use the information from these notes to help
you in creating your own unique presets.

INPUT jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This standard unbalanced ¼” jack provides an input to the Prophesy. This jack has the
same function as the rear panel INPUT jack.
Note that the front and rear INPUT jacks should never be used simultaneously.
This jack should be used when plugging a guitar in and out on a regular basis. The rear
INPUT jack should be used for a permanent input connection, such as in a rack with a
wireless receiver.

About the Effects
Loop
The Prophesy effects loop
allows you to patch a series
of one or more other effect
units into the Prophesy's
signal path at a location
determined by the user.
An example of an effects
loop configuration is shown
in Section 4: Connections.
OUTPUT TO TUNER jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This standard, unbalanced ¼" mono jack provides the same signal that is applied to
the INPUT jack (1) for use with an external electronic tuner.
3
LOOP SEND jacks
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
The Left and Right LOOP SEND jacks provide left and right output signals to be fed
to the left and right inputs of the first outboard effects device in the effects loop.
4
LOOP RETURN jacks
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
The Left and Right LOOP RETURN jacks receive the left and right output signals
from the outputs of the last outboard effects device in the effects loop.
5
MAINOUT jacks
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
These ¼” mono jacks are used to connect the Prophesy to the inputs of a stereo
power amplifier. The output level of these jacks is controlled by the OUTPUT
LEVEL control on the front panel.
8
6
RECORDING OUT jacks
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
These XLR connectors provide left and right output signals that are suitable to be fed
directly into a mixing console or recording device. Note that the Prophesy's Speaker
Simulation function operates only on the RECORDING OUT outputs.
The output level of these jacks is independent of the OUTPUT LEVEL control on
the front panel and is only effected by internal parameter settings. This would allow
you to adjust your stage volume through the MAINOUT jacks without changing the
level to the mixing board.
7
POWER jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This 4-pin DIN connector accepts power from the 9VAC adapter supplied with the
unit.
8
FOOT SWITCH jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This ¼” TRS jack allows for the connection of a dual function, latching-type
footswitch. One function provides the Mute function, while the other provides the
Tap Delay function.
G
About MIDI chains
Inherently in MIDI there is a
limit to the number of
devices which can be
chained together (series
connected). With more than
three devices, a slight
distortion of the MIDI signal
can occur (due to signal
degradation) which can
cause an error in MIDI
signal transmission.
Should this occur, a MIDI
box can be used which
connects directly to the
device transmitting MIDI
information. A MIDI box has
multiple connectors for the
multiple devices receiving
MIDI.
Note that MIDI cables
should not exceed 50 feet (15
meters) in length.
9
PHANTOM jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This jack provides the ability to power a Rocktron MIDI Mate™ foot controller from
a seven pin MIDI cable which connects from the MIDI Mate to the MIDI IN jack on
the rear panel of the Prophesy—thus eliminating the need to find an AC outlet near
where the footpedal would be placed during a performance, or the need to run an
extension cord out to the MIDI Mate.
Instead of inserting the adaptor into the MIDI Mate POWER jack, plug it into the
PHANTOM POWER jack on the Prophesy. This will power the MIDI Mate through
pins 6 and 7 of the MIDI cable connecting the two units. A 7-pin MIDI cable must
be used for this feature and is available through your Rocktron dealer.
10
MIDI IN jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This 7-pin DIN connector receives MIDI information from the device which is
transmitting the MIDI commands for the Prophesy to execute.
11 MIDI OUT/THRU jack
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
This standard 5-pin DIN connector passes on the MIDI information that is received
at the MIDI IN jack to other MlDI-compatible devices via a MIDI cable. It also
outputs MIDI data when performing a memory dump.

5. Basic Operation
Preset Basics
The Prophesy provides 127 unique, stored sounds called presets. Each Prophesy preset
remembers effect settings, mixer settings and MIDI information which can be recalled at any time.
Presets are instantly recalled when accessed via the front panel PRESET control or a MIDI
footswitch. When a preset is selected, the Prophesy will display the preset number, channel, title,
and any additional effects that have been assigned to the preset which aren't automatically
included with every preset (HUSH, compression, wah, tremolo and reverb are automatically
included with every preset). Active effects are indicated via illuminated buttons at the right of the
display, as shown below:
G
Note
The first preset page
displays any effects that
are user-assigned to the
current preset (that aren't
automatically included).
Effects that are active in
the signal path are
indicated by the
corresponding lit buttons
to the right of the display.

CHORUS->PITCH->
----->
-----
Figure 5-1: Display shows preset number (122), preamp channel ("Mega Drive"), preset
title ("Hot Lead") and assigned effects (Chorus, Pitch Shift).
The sound of a particular preset is dependent upon the preamp channel that is selected,
which effects are selected, and how each of those effects is configured. Each effect provides
numerous parameters that can be edited to change its characteristics, and therefore change the
sound of the preset.
13
Preset Pages
The initial information that is displayed when a preset is recalled represents the first page for
the preset. All remaining parameters for the preset (i.e. mixer parameters, effect parameters, etc.)
are located on subsequent pages which are accessible via the front panel PAGE control. Many
pages can also be instantly accessed by the corresponding buttons to the right of the display.
Each preset page displays up to six parameters for a particular effect or function, each of
which can be edited to change the sound of the preset. Note that some effects and functions
(such as reverb and the mixer) have many editable parameters, and therefore occupy numerous
successive pages.
Turning the PAGE control will scroll through the successive pages of the current preset. The
pages for each preset are organized as shown in Figure 5-2.

Effect Configuration
Of the eight possible effects per preset, three are configured as pre-effects (located before
the gain section in the signal path) while the remaining five are post-effects (located after the
gain section), as shown in Figure 5-5 below.
Figure 5-5: Simplified Prophesy effect configuration
You can think of the pre-effects like the stomp-boxes that you would normally connect
between the guitar and the input of an amplifier (before any gain is applied to the signal)—
effects like phasers, wah pedals and compressors. Post-effects are those that you would run
through the effects loop of the amp (after gain has been applied to the signal)—these include the
higher-end processing units which provide effects such as reverb, delay and chorus. However,
you are free to assign any available effects to any of the user-assignable locations designated in
Figure 5-5.
17
Assigning Effects to a Preset
The user-assignable Pre Effect and Post Effect pages each begin with a simple page which
displays the effect currently assigned to the respective location, as shown in Figure 5-6. The unit
will display "EMPTY" if no effect has been assigned to the location, as shown in Figure 5-7.

Note!
It is not necessary to store
changes made to a
particular page before
accessing another page of
the same preset, as all
changes remain in memory
until another preset is
recalled.
However, it is important to
note that any changes
made to a preset will be
lost if another preset is
recalled before those
changes are stored.
—————————————————————————————————————————————
2 The display should look like Figure 5-6 if an effect has already
been assigned to the selected location, or like Figure 5-7 if one
has not. The control labeled "GAIN" can be used to scroll

Assignable Effects Loop
In addition to assigning Prophesy effects to the locations noted as "User-assignable" in
Figure 5-5, the rear panel effects loop can also be assigned to any of these locations instead of
an internal Prophesy effect. This effectively inserts any outboard effect(s) into the Prophesy
signal path wherever you define!

HUSH® Page
HUSH® is Rocktron's patented single-ended noise reduction system, and is available in all presets. The HUSH system provided in the Prophesy is a fully digital implementation, modeled after the latest analog HUSH design, achieved through Digital
Signal Processing (DSP).
How HUSH® works
The low level expander of the HUSH system operates like an electronic volume control. The analog version of the HUSH system utilizes a voltage-controlled amplifier (VCA)
circuit which can control the gain between the input and the output from unity gain to 30,
40 or even 50dB of gain reduction. When the input signal is above the user-set threshold
point, the VCA circuit remains at unity gain. (This means that the amplitude of the output
signal will be equal to that of the input signal.) As the input signal level drops below the
user preset threshold point, downward expansion will begin. It is at this point that the
expander acts like an electronic volume control, gradually decreasing the output signal
level relative to the input signal level. As the input signal drops further below the threshold
point, downward expansion increases (see figure below). A drop in the input level by
20dB would cause the output level to drop approximately 40dB (i.e., 20dB of gain reduction). In the absence of any input signal, the expander will reduce the gain so that the
noise floor becomes inaudible.
The HUSH circuit is located after the A/D converter in the signal chain to reduce any
noise generated from the guitar and the A/D converter. This ensures a quiet input signal to
the preamp section. Because the preamp section of the Prophesy is digital, it is virtually
noise-free (even in the high-gain mode). Therefore, a quiet input signal to the preamp will
result in a quiet output signal.

PARAMETER
HUSH
DESCRIPTION
The HUSH parameter determines whether the HUSH® circuit is active for the
current preset. (Off, On)
HUSH THRESH
The HUSH THRESHOLD parameter determines the level at which downward
expansion begins. For example, if the HUSH THRESHOLD was set at -20dB and
the input signal dropped below -20dB, downward expansion would begin. (-90dB
to -27dB)
GLB OFFSET
The GLOBAL OFFSET parameter allows you to globally (all presets) adjust the
HUSH® expander threshold. This means that if this parameter is altered from 0dB
to +3dB, the expander threshold will become 3dB higher for all presets. This
feature is useful when switching from a quiet guitar with passive electronics to a
noisier guitar with active electronics, as the guitar with active electronics would
require a higher threshold level in all presets. (-10dB to +30dB)
Application Notes: HUSH
You may find that the HUSH is not even needed for tones created with the Clean American voicing
or the Texas Blues voicing when using a low gain setting. As you move into a higher gain Texas
Blues setting or the Vintage British and Mega Drive voicings, the gain rises and so does the noise
floor. The higher the Gain parameter of these voicings is set, the more noise you'll hear. Before
turning on the HUSH and adjusting the HUSH threshold, make sure you have the preamp gain and
EQ settings the way you want them for that preset, then engage the HUSH.
To properly set the HUSH THRESHOLD:
Set the Threshold level so that your signal remains open during the quietest notes or decay's that
you'll be playing, yet shuts down tight when you mute your strings.
Using different guitars:
It is also important to note that if you switch guitars during a performance and those guitars have a
different output level, you should quickly use the INPUT LEVEL control on the face of the unit to
set a proper input level for each guitar. This will allow your preset HUSH Threshold settings to
work the same for all guitars. You may also use the GLOBAL OFFSET to fine tune the HUSH
Threshold settings for all presets.
25
COMPRESSOR Page
The compressor allows you to compress the signal prior to the distortion stage.
Compression is often used to maintain an even volume level when using clean tones, and
is also used to increase sustain when using distorted tones.

C-THRESH
The COMPRESSOR THRESHOLD parameter determines the input level (in dB)
at which compression will begin. Lower settings of this parameter will result in
more compression. (-30dB to -6dB)
C-ATTACK
The COMPRESSOR ATTACK parameter determines the speed (in milliseconds)
in which the compressor will reach its maximum compression level after the input
signal has exceeded the threshold level (set by the Compressor THRESHold
parameter). (0 to 75ms)
C-RELEASE
26
DESCRIPTION
The COMPRESSOR RELEASE parameter determines the speed in which
compression will cease after the input signal has dropped below the threshold
level. (.05sec to 2.05sec)
Application Notes: Compression
Compression is most often used when playing with a very clean tone, like in the Clean American or
Texas Blues voicings. Since there is very little or no clipping (distortion), the guitar signal will
remain very dynamic, which means that there is a lot of variance in volume levels. For example,
when you strum a chord or pick a note, it sounds very loud at first and then dies out quickly. What
compression will do is narrow the dynamic range of the signal, meaning that your strum or pluck
will not be as loud and the decay of the chord or note will be louder. The result is greater sustain
and a more even volume level.
Since the Vintage British and Mega Drive voicings have more gain, there is more clipping of the
guitar signal (distortion). This clipping of the guitar signal is actually a natural form of compression — this is the reason your chords and notes will sustain much longer using high gain than
when using a clean channel. Compression is not usually used with high gain settings, although
you can use it if you really need to get even more sustain and/or for a less dynamic effect and
sound.
Using different guitars:
It is also important to note that if you switch guitars during a performance and those guitars have a
different output level, you should quickly use the INPUT LEVEL control on the face of the unit to
set a proper input level for each guitar. This will allow your preset Compression threshold settings
to work the same for all guitars.

WAH Page
The Prophesy includes an internal wah-wah which can either be used as a fixed
wah or can be controlled by an expression pedal through continuous control changes.
Use of this feature eliminates the need to run long audio cables out to a conventional
wah-wah pedal.
To set up an expression pedal as a wah-wah pedal, the Prophesy must be configured
so that the expression pedal controls the "WAH FREQ" parameter described below. (See
"Controller Assignments" in Section 7 for more information.)

The CHANNEL parameter allows you to select any of the four preamp
channels (1-4) for the current preset. The name of each channel is displayed
under the VOICING TYPE heading when selected. Available preamp
channels are Clean American, Texas Blues, Vintage British and Mega Drive.
V-CN
The V-CN parameter defines a dedicated MIDI controller number for the
Prophesy's volume. A MIDI expression pedal can be configured to match
this number and act as a volume pedal. (0-120)
RUN STAT
The RUN STAT parameter determines the current running status of the
volume pedal. If this parameter is set to "ON" and a preset is recalled, the
Prophesy will set the volume of the recalled preset to the last value it had
received from the volume pedal. When set to "OFF", the Prophesy will recall
the stored preset volume regardless of the current volume pedal position.
Once a preset has been recalled, the volume pedal can be used to change the
volume.
V-PED
The V-PED parameter displays the volume that will be used when the preset
is recalled and the RUN STAT parameter is set to "OFF".

section is a shelving-type. (-15.0 to +12.0)
PRELFF
The PRE LOW FREQUENCY FREQUENCY parameter allows you to select a
frequency band with an upper frequency between 63Hz and 500Hz to be cut or
boosted by the pre-LF LEVEL parameter.
PREMF
The PRE MID FREQUENCY level parameter allows you to cut or boost the
mid-band frequencies from -15dB to +12dB prior to the distortion stage.
PREMFF
The PRE MID FREQUENCY FREQUENCY parameter allows you to select a
mid-band center frequency between 63Hz and 8kHz to be cut or boosted via the
Pre Mid Frequency level parameter.
BW
The BANDWIDTH parameter determines how wide or narrow the bandwidth
of the selected mid-band frequency is (in octaves). A small bandwidth only
boosts or cuts frequencies close to the center frequency, while a large bandwidth
affects the level of frequencies up to two octaves from the center frequency.
(0.1 to 2.5)
BRIGHT
The BRIGHT parameter is displayed only when Channel 1 (Clean American) is
active, and allows you to add extra brightness to the clean channel when
switched on.
Application Notes: Pre EQ
Since the PRE EQ affects the way your guitar signal sounds before it enters the preamp stage, its
effect is most useful to influence the way the way high gain distortion tones will respond. The
more gain you use, the more distortion you get, which can decrease your pick attack. Boosting
mid-range frequencies with a medium bandwidth and dipping some bass can bring back the attack
of your pluck.
Another example of using the PRE EQ would be to create a stomp box overdrive effect by cranking
up the mid frequency level and using a very wide bandwidth while reducing the low frequency.
Another cool effect is to crank up the Pre Low Frequency Level with a Frequency setting of around
155Hz — this will produce a fuzz pedal tone if using with high gain.

varying. Using different detune amounts, modulation rates, modulation depths and pan
settings for each delayed signal will produce a greater perceived spaciousness.

FASTSP
The FAST SPEED parameter sets the fast rotation speed. (0 to 100)

accelerate faster than the rotor). (0 to 100)
ROTBAL
40
The ROTATION BALANCE parameter adjusts the relative level of the rotor
(lows) vs. the horn (highs). (Rotor to Horn)
Application Notes: Rotary
The Rotary effect included in the Prophesy has been designed to provide the most realistic
simulation of an actual rotary speaker as possible. However, the nature of the rotary effect requires
a significantly higher amount of processor power than any of the other effects included in the
Prophesy in order to implement it without sacrificing the quality of the effect.
As a result of this, it is important to note that using all three modulation effects (rotary, flanger,
chorus) and the phaser effect simultaneously can result in an overload of the Prophesy's internal
processor—causing a significant hum and loss of sound quality. For this reason, it is recommended
that simultaneous usage of all three modulation effects is avoided to greatly reduce the chances of
this condition occurring.

PITCH SHIFT Pages
Pitch Shifting is used to change the pitch of the input signal to produce a harmony
note based on the input signal. The Prophesy allows for 2 harmony voices to be defined
for each preset. Each harmony voice can be of any fixed interval—up to one octave
above the input signal to two octaves below—and is selected in 20-cent increments.
Fine adjustment can be made in one cent (1/ 100th semitone) increments.

DESCRIPTION
The PITCH parameter selects what harmony note the Prophesy will produce
based on the input note. The value displayed for this parameter represents the
number of cents that the signal will be shifted (adjustable in 20-cent increments).
Each 100 cents (or five 20-cent steps) above or below “0” represents the number
of half-steps the shifted signal will be from the input signal.
This parameter is adjustable from -2400 to +1200, where -2400 = two octaves
below the input signal, 0 = unison and +1200 = one octave above the input signal.
Refer to the table below to determine the cent value for each fixed interval.

DUCKER/DELAY Pages
Delay is a repeat of the guitar signal, which will repeat at the time the user sets
(typically expressed in milliseconds) after the original guitar signal. The Prophesy
provides several parameters to adjust the characteristics of the delay effect.
About Ducking
The Delay effect also has a built-in Ducker function. The word "ducking" is
another way to say that you're turning down the volume level of the delay (or "attenuating" the delay). When using the ducker, the volume of the delay would be attenuated, or
"ducked" while playing so that it was quieter than your original played notes and,
therefore, would not compete with your played notes. When you stop playing, the ducker
will release and the volume level would then come back to full volume and echo out nice
and loud. The Ducker effect does this for you automatically! This is a great effect for
soloing. When the ducker is adjusted correctly, you can have the delay mixed just right
behind your played notes and have nice loud and long trail-offs when you stop playing.

MUTE
DESCRIPTION
The MUTE parameter allows for muting of the Delay section at its input (PRE),
its output (POST) or both pre and post (BOTH). (The MUTE function is
actually switching the Delay IN and OUT — just like you would with the Delay
button on the front panel. It can be accessed with a MIDI pedal by sending the
Prophesy a MIDI control number of your choice and assigning that same MIDI
control number to the DELAY-IO parameter in any of the Prophesy's eight
Controller Assignments. See "Controller Assignments" in Section 7 for more
information.)
When using the MUTE "PRE" setting, the Delay IN/OUT function will start and
stop the guitar signal before it enters the delay effect. This will produce the
following results: When you switch the delay "OUT" while you're playing, the
guitar signal will be stopped from entering the delay effect at its input and the
last few notes you were playing will trail off until there is no more delayed signal.
When switching the delay "IN", signal will begin to enter the delay effect and will
then start to be delayed from the exact point at which you turn the delay on.
45
Delay Page 1 parameters (cont'd)
PARAMETER
DESCRIPTION
When using the MUTE "POST" setting, the Delay IN/OUT function will start
and stop the guitar signal at the delay effect's output. This will produce the
following results: When you switch the delay "OUT" while you're playing, the
delayed signal will suddenly be chopped off and will no longer be heard. The
delay effect's input, however, is still receiving signal. So, when you switch the
Delay "IN" while playing, any licks you were playing will already be echoing and
will then be heard.
When using the MUTE "BOTH" setting, the Delay IN/OUT function will start
and stop the guitar signal at the delay effect's input and output. This will
produce the following results: When you switch the delay "OUT" while you're
playing, the delayed signal will suddenly be chopped off and will no longer be
heard. When switching the delay "IN", the signal will begin to enter the delay
effect and will then start to be delayed from the exact point at which you turn the
delay on.
SPILOVR
The SPILOVR parameter determines whether delays from the current preset will
"spill over" into the next preset when it is recalled. If this parameter is set to
"OFF", delays from the current preset will be immediately cut off when another
preset is recalled.
When this parameter is set to "ON", it enables the current delay to "spill over" to
the next preset. However, note that in order for the spillover to work, the Delay
effect must be assigned to any of the effect assignments in the next preset that you
switch to. Also, the Delay SPILOVR parameter must be stored as "ON" in that
next preset. You do NOT have to have the delay stored as "ON" in the next preset
unless you want to. For example, this can create a very smooth transition from a
very long lead solo delay into a nice short rhythm delay, where the long delay
trails out as the new shorter delay has already begun. If Delay has not been
assigned in the next preset that you switch to, the spillover will not work.(Off,
On)
LEVEL
PAN
46
The LEVEL parameter determines the overall level of the delayed signal at the
output relative to the direct signal and other effect signals. (Off, -42.0 to +6dB)
The PAN parameter allows for the delayed signal to be panned to the left or right
channel. (Left to Right)
D-TIME
The DELAY TIME parameter determines the length of time (in milliseconds)
after the input signal that the delayed signal will begin. (0 to 988)
REGEN
The REGENERATION parameter determines the number of times that the
delayed signal will repeat itself. This is achieved by feeding the delayed output
back into the input. Higher parameter settings will result in more repeats. The
displayed value represents the attenuation (in dB) that the regeneration signal is
subjected to at each repeat. (Off, -42.0 to +6dB)

DESCRIPTION
HF DAMP
The Delay HIGH FREQUENCY DAMPING parameter controls the amount of
high frequency content in the delayed and regenerated signals. Higher amounts of
damping will result in less high frequency information in the delayed signal.
Application Note:
Using little or no High Frequency Damping will render a perfect, mirror like
delay. Medium to high amounts of High Frequency Damping will produce a
duller, more tape echo-like delay sound. (0 to 99)
DUCK
The DUCKER parameter determines whether the Ducker is active or muted for
the current preset. (Off, On)
SENS
The SENSITIVITY parameter determines the threshold point above which the
ducker will begin attenuating the delay signal. Until the input reaches this level,
the delay signal will not be affected by the ducker. (-92dB to -20dB)
ATTN
The ATTENUATION parameter determines how much the delayed signal is
attenuated (muted). It may be set for only a slight change in signal level or it can
completely attenuate the delayed signal so that no delayed signal passes while
ducking is active. (INFIN, -48 to -0.0)
REL
The RELEASE parameter determines the length of time it takes for the for the
muted delay signal to return to its original level after the input signal falls below
the threshold point set by the SENSitivity parameter. (.2 to 9.0)

DESCRIPTION
T-DPTH
The TREMOLO DEPTH parameter determines the amount of modulation for
the Tremolo signal. Lower depth settings produce more subtle tremolo effects,
while higher settings will result in a more extreme tremolo effect.
T-RATE
The TREMOLO RATE parameter determines the speed at which the tremolo
signal modulates (or increases and decreases in volume).
T-SHAPE
The TREMOLO SHAPE parameter determines the waveshape of the tremolo
signal. Selecting a different waveshape produces a different tremolo effect.
{TREMOLO}
The {TREMOLO} parameter determines whether the tremolo effect is before
(PRE-REV) the reverb or after it (PST-REV) in the effects chain. Refer to the
block diagram shown in Chapter 5 for more information on the Prophesy signal
path.
REVERB Pages
Reverb is a multitude of echoes that are spaced so close together that, to human
ears, seem as a single continuous sound. These echoes gradually decrease in intensity
until they are ultimately absorbed by the boundaries and obstacles within a room. As
the sound waves from the sound source strike the boundaries of a room, a portion of the
energy is reflected away from the obstacle while another portion is absorbed into it —
thereby causing both the continuance of sound as well as the decaying or “dying out”
of the sound.
Reverb Types
The Prophesy provides the following types of reverb:
• The Plate reverb type simulates an artificial method of producing reverberation,
popular in the early years of recording, which involved using a fairly large, but
very thin, metal plate suspended at its four corners by steel wires under
tension. This metal plate becomes excited by a driver unit (similar to a dynamic
speaker without the diaphragm) and the resulting reverberation is picked up by
contact microphones.
The Prophesy offers two Plate reverb types which reflect the most common
plate characteristics. This type of reverb is often used on drum and vocal tracks.
• Room reverb effects simulate various rooms of different sizes and surfaces. For
example, a room which is made up of primarily hardened surfaces (such as tile
or hard wood) will generate reflections containing much more high frequency
information than one which is made up of softer surfaces (such as thick
carpeting). The Room reverb effects provided by the Prophesy can generate
virtually any imaginable room setting via highly efficient and adjustable reverb
parameters.
• Hall reverb simulates the reverberation characteristics of a very large room with
a high ceiling. Reflections in a hall are much longer than a typical room, as the
length of time it takes for the sound waves to travel from one surface to the
next is greatly increased.
• Stadium reverb simulates the characteristics of a large stadium or arena and
should be used with large amounts of predelay and high frequency damping.
• Dual reverb is unique in that it allows for the left and right channels to be
processed independently of one another. For example, the predelay for the left
channel can be set at 100mS while the Predelay for the right channel can be
set at 200mS. This results in reverb output from the left channel 100mS before
reverb is output from the right channel.

The REVERB PAN parameter allows you to pan the direct input signal to the
reverb section to the left or right—thus allowing for only the left or right channel
to be reverberated when used with the Dual reverb type, or, for one channel to be
reverberated to a greater degree than the other. It is adjustable from LEFT (0) to
RIGHT (100), where 1-49 appear between LEFT and CENTER, and 51-99
appear between CENTER and RIGHT.
R-DEC
The REVERB DECAY parameter specifies the length of time that the reverb
signal will sound before it has completely "died out". Note that the maximum
length of this decay will vary dependent upon the reverb type currently active. (0
to 99)
HFDMP
The HIGH FREQUENCY DAMPING parameter is used to control the decay
rate of high frequency information in the reverb signal. Higher parameter settings
will result in a faster decay of high frequency information. (0 to 99)

PARAMETER NAME
DESCRIPTION
PREDLY L
The PREDELAY LEFT parameter determines the length of time after a signal is
input to the Prophesy that the left channel signal will be input to the reverb
section. Delaying the reverb signal provides greater separation of the input and
reverb signals, and helps to increase the perceived size of the Room, Hall or
Stadium. (0 to 198)
PREDLY R
The PREDELAY RIGHT parameter determines the length of time after a signal is
input to the Prophesy that the right channel signal will be input to the reverb
section. Delaying the reverb signal provides greater separation of the input and
reverb signals, and helps to increase the perceived size of the Room, Hall or
Stadium. (0 to 198)
GATE
The GATE parameter closes down the decay of the reverb very quickly after a
prescribed amount of time (most commonly a very short period of time). Note
that the gating on the Prophesy acts on the reverb decay, rather than the reverb
output as on many other units. (Off, On)
G-DEC
The GATE DECAY parameter determines how quickly the gate will close down
the reverb decay after the reverb has sounded for the specified time. (0 to 31)
G-THR
The GATE THRESHOLD determines the signal level at which gating will take
place. When the signal remains below this threshold level for the specified HOLD
time, the reverb will be gated. When the input signal peak rises above this
threshold, the gate will open and reverb will be heard. (Off, -42.0 to +6.0)
HOLD
The HOLD parameter determines how long the reverb signal will sound before
the gate begins to close. (0 to 99)

Application Notes: Post Effect Mixing
The PST2-IN MIX and PST3-IN MIX parameters act as a balance between the direct and effect that
is entering the assigned effect of Post effect blocks 2 and 3. For example, lets say that DUCKER/
DELAY is assigned to Post 1 effect block and that CHORUS is assigned to Post 2 effect block.
Adjusting the PST2-IN MIX parameter to 100% DIRECT would cause only the direct guitar tone to
be chorused while the delayed signal would not be chorused. Adjusting the PST2-IN MIX
parameter to 100% EFFECT would cause only the delayed signal to be chorused while the direct
guitar tone would not be chorused. Adjusting the PST2-IN MIX parameter anywhere between
DIRECT and EFFECT would cause a blend of the direct and the delayed signal to be chorused.

The DPAN parameter is used to pan the direct signal to the left or right
Prophesy output. (100% Left to 100% Right)
OUTPUT
The OUTPUT parameter determines whether the output of the Prophesy is
a stereo (left and right) signal or two mono signals.
PLEVEL
The PRESET LEVEL parameter determines the overall output level of the
current preset relative to the other Prophesy presets.
Application Notes: Reverb Mixing
The DIR (Direct) parameter actually controls the volume of the DRY guitar signal (with no effect) at
the output. This can become very useful when attempting to get a wetter effect sound — rather
than cranking up all your effects levels, simply turn down the DIR parameter to remove some dry
guitar signal. The result will be thicker, richer sounding chorus, rotary, flanger, etc.
The OUTPUT control is global, which means that it effects all presets. When set to "STEREO", all
effect and direct signal panning will be directed toward their respective Left and Right Recording
and Main outputs. The "STEREO" setting should be used when connecting the left and right
outputs to individual channels of a stereo power amp and then to a stereo speaker cabinet. When
set to "MONO", all effect and direct panning is ignored and all signals are directed to the Left and
Right outputs evenly. Use the "MONO" setting and either the Left or Right output for use with a
mono amp head and non stereo speaker cabinet, or when you wish to mic only one speaker.
The PLEVEL (Preset Level) control should be used only for additional preset level matching. The
MASTER control of the first Preamp page is your first and most easily accessible level setting for
each preset, however, you may find that some clean presets with a very low gain setting are very
quiet, even with the master set to 10. High gain presets will be much louder in relation to these
ultra-clean presets. This parameter simply gives you an added preset level control in addition to
your channel masters.
57
CONTROLLER Pages
Controller assignments allow for specified Prophesy parameters to be mapped (or
assigned) to a MIDI controller for real-time control by an expression pedal or by the
controller on/off buttons of a MIDI foot controller. In addition to 120 MIDI control
numbers, you may assign the Prophesy's ADSR (Attack/Sustain/Decay/Release) control
effect to any parameters with these controller assignments (ADSR is discussed further in
Section 7, Using the ADSR).
Controller assignments also allow you to store an upper and lower parameter value
limit which the controller cannot exceed. For example, when using the expression pedal
to send continuous control changes to control the “PITCH 1” parameter, an upper
limit of +300 can be set and a lower limit of -200 can be set—even though the actual
parameter range is from +1200 to -2400. When the expression pedal is at its heel
position in this example, the “PITCH 1” parameter will be at -200, while at its toe
position it will be at +300. (Refer to Section 7: “Using the Prophesy” for information on
setting up controllers.)
Up to eight controllers can be assigned for each individual preset, and each one has
its own display page.

TAP BUTTON Page
The Tap Button function allows for delay times and tremolo rates to be set by
tapping the front panel TAP button, by a momentary footswitch connected to the rear
panel, or by a control button on a MIDI foot controller like the Rocktron All Access.
Obviously, this is very handy for quickly getting the proper Delay times and/or Tremolo
rates for different song tempos.
The Tap Button page determines which effects that the Tap function will operate on.
The Tap function can work with the Delay time, the Tremolo rate, or both simultaneously. These settings will work the same for the front panel Tap button, a momentary
footswitch connected to the footswitch jack, or control messages sent by a MIDI foot
controller.
It is also important to note that: The TAPBTN (Tap Button) parameter settings of
DELAY, TREM or BOTH will only operate as set when viewing any other page except the
delay or tremolo pages. So, for example, if the TAPBTN parameter is set to BOTH and
you're presently viewing the preset title page, and you were to begin tapping the TAP
button, the Delay time and Tremolo speed will be adjusted simultaneously. However, if
you then turn to the Delay page and begin tapping the TAP button, it will effect the
Delay time only. Likewise, viewing the Tremolo page and tapping the TAP button will
effect the Tremolo rate only.

QUANT
The QUANTize parameter determines how the Tap function sets the delay
time and the tremolo rate. For example, when set to "1/4 NOTE", the delay
time will be set to match the same tempo that you tapped. When set to "1/
8 NOTE", the delay time will be twice as fast as the tempo that you tap.
Likewise, the Tremolo rate may be quantized in the same fashion, allowing
one to quickly get the proper tremolo rate for the tempo of a particular song.
What if I want a 1/16 note? Simply multiply a 1/8 note tapped speed or rate
value by 2 and adjust it by hand! (1/8 Note, 1/4 Note)
T-CTRNUM
T-LED
This parameter sets a dedicated controller number for the Tap function,
allowing you to set delay times from a MIDI controller. (0 - 119)

Storing modified presets
A modified preset must be stored in order for the changes that have been made to be
activated the next time the preset is recalled.
———————————————————————————————————————————————————
1 To save any changes that have been made to a preset, press the STORE
button once to initiate the storing procedure. The Prophesy will display
"SELECT DESTINATION PRESET". This allows you to store the
modified preset into a new location and save the original preset at its
present location.
SELECT DESTINATION PRESET
———————————————————————————————————————————————————
2 If you wish to save the new preset to a new preset number, use the
PRESET control to select the new preset number. Note that the preset
currently stored at the newly selected location will be written over once
the storing process is completed. If you decide at this point that you do
not wish to store the preset, you may turn the PAGE control to cancel
the storing process.
If you do not wish to store the new preset at a different preset number,
skip this step. Note that the preset stored at the current location will be
written over once the storing process is completed.
———————————————————————————————————————————————————
3 Once the desired preset number has been selected, press the STORE
button a second time. The Prophesy will display "STORING PRESET
NOW" as it is storing the information, and "PRESET HAS BEEN
STORED" when it is finished.
****** PRESET HAS BEEN STORED *****
Now the modified preset has been stored to the specified preset number
and can be recalled at any time.
67
Naming presets
The Prophesy display provides up to 20 characters that can be used to configure a
title (or unique name) for each preset.
———————————————————————————————————————————————————
1 Use the PAGE control to access the Title Edit page. (The Title Edit
page looks just like the first preset page, but without the assigned
effects displayed).
A cursor will appear below the first character of the displayed title, and
the entire character space will flash—indicating the current character
position to be edited.

69
Using Controller assignments
Controller assignments allow for specified Prophesy parameters to be mapped (or
assigned) to a MIDI controller for real-time control by an expression pedal or by the
controller on/off buttons of a MIDI foot controller. In addition to the 120 possible MIDI
control numbers, you may also assign the Prophesy's ADSR (Attack/Decay/Sustain/
Release) control effect to any parameter with any of the 8 controller assignments (ADSR
is discussed in detail in the section titled "Using the ADSR" later in this chapter).
The Prophesy's controller assignments also allow you to store an upper and lower
parameter value limit which the controller cannot exceed. For example, when using the
expression pedal to send continuous control changes to control the “PITCH 1”
parameter, an upper limit of +300 can be set and a lower limit of -200 can be set—even
though the actual parameter range is from +1200 to -2400. When the expression pedal is
at its heel position in this example, the “PITCH 1” parameter will be at -200, while at
its toe position it will be at +300. The example which follows will detail configuring a
controller in this manner.
Up to eight controllers can be assigned to each individual preset.
———————————————————————————————————————————————————
1 Use the PAGE control to access the first Controller page. Note that the

Reversing upper
and lower limit
settings
The upper and lower limit
parameter values can be
reversed, so that the upper
limit parameter actually
holds a lower value than the
lower limit value.
This effectively reverses the
operation of the MIDI
controller, such that the toe
position of a footpedal
would produce the lowest
value, and the heel position
would provide the highest
value.

each time the current preset is recalled.
You may now use the PAGE control to access the next controller page
and repeat Steps 2-6 to configure another Prophesy parameter to be
controlled by a MIDI controller, if desired. Up to 8 controllers can be
configured per preset.
71
Using ADSR
What is ADSR?
ADSR stands for Attack/Decay/Sustain/Release. The advanced ADSR function featured in the
Prophesy provides a powerful degree of control over any user-specified parameter while playing.
The Prophesy's ADSR function operates differently than previous ADSR circuits1, as it utilizes
Rocktron's patent-pending pluck detection to trigger the ADSR function as you play. That is, each
time a string is plucked on the guitar, the Prophesy detects it and triggers the ADSR circuit, which
then varies the value of a specified parameter as defined by the settings configured on the ADSR
page.
To use the ADSR function, you must configure a controller assignment (as described in the
previous section) for a Prophesy parameter that you wish to control, using "ADSR" as its controller
number. Here you can also define upper and lower parameter limits which determine the range that
the ADSR function will operate over.
Once the controller assignment has been made, you can assign ADSR to one of the assignable
effect locations (Pre Effect, Post Effect 1-3), then go to the preset's ADSR page and define what
happens to the assigned parameter each time a string is plucked.
There are five parameters which determine how ADSR interacts with an assigned Prophesy
parameter. These are as follows:
—————————————————————————————————————————————————————
ATTACK
Determines the length of time for the assigned parameter to
reach its maximum value (or the upper limit value set by the
controller assignment, if set) once a plucked string is detected.
DECAY
Determines the length of time for the parameter value to decay
from the peak ATTACK value to the value set by the S-LVL
(Sustain Level) parameter.
S-TIME
Determines the length of time that the parameter will sustain
(remain) at the value set by the S-LVL parameter.
S-LVL
Sets the sustain level (or parameter value) at which the assigned
parameter value will be sustained for S-TIME milliseconds. This
value can be set from 0 to 127, with 0 representing the minimum
parameter value available and 127 representing the maximum
value.
R-TIME
Determines the length of time it takes for the assigned parameter to return to its minimum value from the value set by the SLVL parameter.
—————————————————————————————————————————————————————
1
72
Older implementations of ADSR utilized a threshold-based method of triggering the ADSR function, rather
than pluck detection. Threshold-based implementations are less effective, as many notes can be plucked
that go unnoticed by the detection circuit and never trigger the ADSR function.
Figure 7-1 is a graph of a typical waveform that the ADSR function might generate, where the
line which moves across the graph represents the value of the assigned Prophesy parameter after a
string is plucked. Here you can see the role that each parameter plays in determining ADSR
operation.
Figure 7-1: Typical ADSR waveform
ADSR can be used with any Prophesy parameter. One of the many potential uses for ADSR is
the simulation of a wah pedal being pressed each time a string is plucked. To better illustrate the
setup and use of the ADSR function, the remainder of this section will detail the steps involved for
configuring ADSR for use with the WAH FREQ parameter.

That's it! You now have a dynamic, automatic wah pedal effect which simulates pressing and
releasing a wah pedal with every picked note. This is far more effective than a conventional
automatic wah effect, which simply varies the wah frequency up and down based on time (without
recognizing what is actually played). In fact, for many applications using ADSR with the wah effect
can be even more accurate than using an actual wah pedal.
Figure 7-2 shows a graph similar to that shown in Figure 7-1, but with the parameter values
from this example included.
77
Figure 7-2: Graphical representation of example settings
What happens when a note is plucked?

Referring to Figure 7-2, upon the pluck of a string, the WAH
FREQ parameter starts at its lower limit value of 2600Hz and
gradually increases to its upper limit value of 310Hz (remember, the upper and lower limits have been reversed in this
example) over a period of 19 milliseconds.
‚
The signal then decays from the upper limit value (310Hz) to
the value set by the S-LVL parameter over a period of 53ms.
ƒ
The WAH FREQ parameter will hold at the current value for 14
ms, as defined by the S-TIME parameter.
„
After S-TIME has passed, the WAH FREQ parameter will drop
to the value set by the lower limit parameter (2600Hz) over a
period of 12ms.
Note that changing the value of the WAH FREQ parameter as described above is essentially the
same process that occurs when a conventional wah pedal is pressed and released over a period of
98ms (the total time-span shown in Figure 7-2).
Viewing the ADSR effect as it operates
It is possible to actually view the ADSR effect in action by viewing the parameter that the
ADSR is controlling. After completing the setup steps, press the WAH button to recall the Wah page
and you'll actually be able to see the WAH FREQ parameter being adjusted by the ADSR as you
pluck notes! This is also a handy way to identify the actual parameter value that the ADSR's S-LVL
(sustain level) parameter represents. In this example, you'll notice that after the decay, the wah
frequency parameter will stop and hold for 14 milliseconds (S-TIME) at 1297HZ (S-LVL).
78
Using the Tap Button
The Prophesy's Tap Button function allows you to set delay times and/or tremolo rates on-thefly (while playing), either by tapping the front panel TAP button, by a momentary footswitch
connected to the rear panel, or by a control button on a MIDI foot controller like the Rocktron All
Access.
When activated, the TAP function instantly changes the current delay time/tremolo rate
settings based on the length of time between any two taps that are less than one second apart.
Obviously, this can be very handy for quickly getting the proper Delay times and/or Tremolo rates
for different song tempos.
After the Prophesy detects the length of time between taps, it then uses the time detected to
set the D-TIME parameter (displayed on the first Delay page) and/or the T-RATE parameter
(displayed on the Tremolo page). Depending on the value stored in the QUANT parameter of the
Tap page, the resulting delay time will be either:
• equal to the time between taps (when QUANT is set to "1/4 NOTE"), or,
• one-half of the time between taps (when QUANT is set to "1/8 NOTE")
The front panel TAP button flashes continuously to provide a visual indication of the current
delay time setting. (This feature can also be turned off via the T-LED parameter on the Tap Button
display page.)
The TAPBTN parameter on the Tap Button page determines which effects that the Tap function
will operate on. These settings will work the same regardless of whether the Tap function is
initiated via the front panel Tap button, a momentary footswitch connected to the footswitch jack,
or control messages sent by a MIDI foot controller.
It is also important to note that the TAPBTN (Tap Button) parameter settings of "DELAY",
"TREM" or "BOTH" will only operate as set when viewing all other pages except the delay or tremolo
pages. So, for example, if the TAPBTN parameter is set to "BOTH" and you're presently viewing the
preset title page, and you were to begin tapping the TAP button, the Delay time and Tremolo speed
will be adjusted simultaneously. However, if you then turn to the Delay page and begin tapping the
TAP button, it will effect the Delay time only. Likewise, viewing the Tremolo page and tapping the
TAP button will effect the Tremolo rate only.
79
Setting up MIDI Program Changes
MIDI program changes allow for different MIDI program numbers to be assigned to Prophesy
preset numbers. For example, MIDI program #58 can be mapped to Prophesy preset #33. Then,
when program #58 is selected from a MIDI transmitting device (such as a Rocktron All Access foot
controller), preset #33 will be recalled on the Prophesy.
The preset/program change mapping is shipped from Rocktron at a one-to-one correspondence
(i.e., MIDI program #1 is mapped to Prophesy preset #1, 2 to 2, etc.).
The Prophesy can be set to execute program changes as sent from a controller (ON), map
incoming program changes to different Prophesy presets (MAP), or ignore all incoming program
changes (OFF)
Note that the default setting for the Prophesy MIDI transmit channel is OFF in all presets,
therefore no MIDI commands are sent from the Prophesy when a preset is recalled unless it is
configured by the user.

Setting MIDI Channels
The Prophesy can receive MIDI commands from other MIDI transmitting devices. In
order for this function to operate properly, the Prophesy's MIDI receive channel must be
set to correspond to the MIDI channel that the other devices are transmitting MIDI
messages on. This section discusses how to set the MIDI receive channel.

Dumping and Loading Prophesy Data
Any or all of the Prophesy presets can be dumped to a sequencer or another Prophesy via system exclusive messages. The information exchanged when performing a MIDI
dump or load consists of parameter values, title characters and controller assignment/
limit information. When dumping a single preset into another Prophesy, the dumped
preset can be loaded into any preset location on the receiving unit.

when dumping data from one
Prophesy to another.
———————
When dumping data to and
from the Prophesy, always
perform the dump in real
time sequence mode. This
will ensure that data loaded
back into the Prophesy is not
sent faster than the Prophesy
can receive it.
———————
Also, make sure that the
sequencer's MIDI filter is
configured to accept SYSX
information.
———————————————————————————————————————————————————
2 Play back the data stored on the sequencer. The Prophesy will automatically begin storing the information as it is sent from the sequencer,
and will display the data strings as it is storing them. After all the data
has been loaded, the Prophesy will display "LOAD COMPLETE".
